Payton Rae is poses for a portrait Friday, May 20, 2011, in Houston. The 15-year old Houston-based country singer already has a bigger presence online - and across the globe - than some country artists that have recently topped this iTunes chart. Her first ever EP, DARE TO LIVE, charted as high as #4 on the iTunes country chart. With more than 52,000 followers on Twitter, 16,000 "likes" on Facebook and nearly 2.6 million YouTube views at her dedicated channel (over six million combined views) ( Cody Duty / Houston Chronicle )

League City girl Payton Rae is only 15 and already charting on the iTunes charts.

April usually belongs to the Houston International Festival. The 43rd annual event takes over downtown Houston this weekend with music from all over the world.

But a pair of competing events are looking to steal some of that shine. The annual BuzzFest and the inaugural OMG Music Fest boast packed lineups targeting wildly different audiences. (There probably won't be much crossover.)

BuzzFest 30 features two stages of rock-radio heavyweights, including Shinedown, Bush, Stone Sour, Papa Roach and P.O.D. It's a lineup that could have easily worked 10 years ago, too.

After a decade-long absence, Gavin Rossdale's emotive outfit returned in 2011 with "The Sea of Memories." And Papa Roach, like the insect it evokes, never seems to go away. Always lurking somewhere in the dark.

My last BuzzFest experience included pockets of the raucous crowd throwing chairs, trash and blankets all over the venue. No worries, though: The Woodlands security has since tightened things up.

The OMG Music Fest is a decidedly poppier affair, stacked with young acts that have built followings via YouTube and TV singing competitions. Among them is Houston girl Payton Rae, who has more than 85,000 Facebook fans, almost 160,000 Twitter followers and more than 7 million YouTube views. (Almost half of those hits are for her original song "Not Your Cinderella.") Rae's debut EP, "Dare to Live," reached No. 4 on the iTunes country chart.

Also on the OMG lineup is local singer Arabella Jones, rapidly building her own following via viral videos and live shows; Irving teen Brandon Hassan, who was seen on "The X Factor"; and Eben Franckewitz, who made the top 24 during Season 11 of "American Idol."
